On this day in 1865, about 100 Indians from Indian Territory raided a new settlement in Cooke County. Along with stealing "many" horses, 9 people were killed. Five years later, four brothers named Ross established a general store at the site, and a post office was opened in 1872. Local legend maintains the outlaw Sam Bass used the area as a rendezvous, and the town of Rosston still celebrates Sam Bass Day on the 3rd Saturday of July..
